Class A Motorhome Storage: What to Look For (Size, Access & Cost)

Storing a Class A motorhome is fundamentally different from storing a travel trailer or a Class C. The sheer size of a Class A — typically 26 to 45 feet long, 8.5 feet wide, and 12 to 13.5 feet tall — eliminates most storage options that work perfectly well for smaller rigs.

The good news is that facilities designed for large vehicle storage exist in most regions. The key is knowing what to look for so you don't end up at a facility that technically accepts large rigs but can't actually accommodate yours without damage risk.

Understanding Class A Motorhome Dimensions

Before you evaluate any storage facility, know your specific motorhome's dimensions. Don't rely on manufacturer class descriptions — measure your actual rig, including any overhangs, storage bay doors that open outward, or external mounted items like generators.

Key Measurements to Know

• Length: Measure from the front bumper to the rear bumper, including any hitch receiver, tow bar, or cargo carrier mounted on the back. Tag axle models can push length to 40–45 feet.
• Height: Measure at the highest point — usually a roof-mounted AC unit or roof vent. Don't forget that some diesel pushers have a satellite dish that adds another 12–18 inches.
• Width: Measure at the widest point including any exterior mirrors, solar panels, or slideout rooms that may extend when open. Width while driving (mirrors folded) vs. parked (slideouts extended) can differ by 3–8 feet.
• GVWR: Know your gross vehicle weight rating — some storage facilities have weight limits on their paved surfaces or structures.

Space Requirements: What a Facility Must Offer

Length Capacity

Many facilities advertise spaces for RVs “up to 40 feet” but don't clearly state whether that 40-foot measurement accounts for the nose and tail clearance you need to actually park without hitting obstacles at either end.

A 40-foot space is only useful for a 40-foot motorhome if there's at least 5 feet of clear maneuvering room at both ends. Ask specifically: “What is the total available length in the space, and is there clearance room on both sides of the parking area?”

For outdoor lots, spaces that open onto a wide interior road can accommodate longer rigs than the space length alone suggests — you pull in diagonally and straighten up. But this only works if the road is wide enough for the maneuver, which brings us to the next point.

Interior Road Width

The interior roads of a storage facility determine whether you can actually get your Class A in and out without a 27-point turn. A Class A motorhome needs a significantly wider turning radius than a passenger vehicle.

As a general rule:

• Class A motorhomes up to 35 feet need interior roads of at least 30 feet wide to maneuver comfortably
• Class A motorhomes 35–45 feet need interior roads of 35–40 feet or wider, especially for 90-degree turns
• If the facility has a pull-through design (you enter from one end and exit from the other without backing), road width is less critical

Visit the facility during business hours and drive or walk the interior roads yourself before committing. Narrow roads that look fine on paper become a problem the first time you need to leave at night or in tight conditions.

Height Clearance

Height clearance is critical for covered and enclosed storage. Many covered storage structures are designed for travel trailers and shorter Class C motorhomes — clearance heights of 11 to 12 feet are common but inadequate for Class A units with rooftop AC units.

A typical Class A diesel pusher with a rooftop AC stands 12.5 to 13.5 feet tall. Some models with satellite dishes or raised roof lines reach 14 feet. You need a covered structure with at least 14 feet of clearance — and ideally 15 feet — to comfortably accommodate a Class A.

When you call a facility, ask for the actual clearance height of their covered structures, not just a maximum vehicle height. Those numbers should match. Also ask about the entry clearance — some facilities have lower-hanging roof sections at the entrance that are narrower than the interior clearance.

For enclosed indoor storage, the same rules apply — and you should also ask about the overhead door height, which is often a few inches lower than the interior clearance.

Space Width

A Class A motorhome body is 8 to 8.5 feet wide. When slideouts are deployed, total width can reach 14 feet or more. If you plan to work on your RV during storage visits — or if you're doing mid-storage check-ins that require walking around the vehicle — you need side clearance as well.

For comfortable access, look for spaces at least 12 feet wide with the ability to deploy at least one slideout if needed. This is rarely possible in enclosed storage but can sometimes be accommodated in covered outdoor spaces.

Gate Access: Can Your Class A Actually Enter?

This is a detail many owners overlook until they arrive at the facility for the first time. The entry gate must accommodate a Class A's dimensions — including width, height, and turning radius to reach the gate from the street.

• Gate opening width should be at least 14–16 feet for a Class A with mirrors folded
• Any overhead bar or clearance bar at the entry must be higher than your motorhome's total height
• The approach from the street should allow a wide enough turn to align with the gate without clipping curbs or pillars
• If the gate uses a keypad, the keypad should be reachable from the driver's window without exiting the vehicle

Ask the facility operator directly: “Have you had any issues with Class A motorhomes of [your length and height] accessing the facility?” A confident yes — or a specific story about a similar rig that stores there — is reassuring. Hesitation is worth probing.

Surface and Drainage Considerations

Class A motorhomes are heavy — diesel pushers can gross at 50,000 pounds or more when fully loaded. Parking a vehicle of that weight on soft or unstable ground causes the wheels to sink over time, creating a dangerous situation when you try to move out.

Storage surfaces that work well for a 5,000-pound travel trailer may not hold up under a 30,000-pound Class A. Look for:

• Paved asphalt or concrete surfaces — the most reliable for heavy vehicles
• Compacted gravel with a solid base — acceptable if well-maintained and properly drained
• Avoid: loose gravel, unpacked dirt, or grass surfaces for any extended storage period

Also check the drainage. Storage lots in flood-prone areas can see standing water after heavy rain. A Class A parked in a low spot that repeatedly floods will have the undercarriage and storage bays exposed to water — even if the main structure stays dry.

Electrical Hookups: More Important for Class A Owners

Class A motorhomes often have more sophisticated electrical systems than smaller RVs — larger battery banks, residential-style refrigerators that require continuous power, and HVAC systems that benefit from being maintained on shore power.

If your Class A has a residential refrigerator, you essentially must have shore power during storage — residential fridges cannot be simply turned off and left for months without damage. If you have a residential fridge and the storage facility doesn't offer electrical hookups, you need a different plan (generator or solar to maintain a large battery bank, or transitioning to the RV's propane absorption fridge).

Our guide to RV storage with electrical hookups covers why shore power matters and how to find facilities that offer it.

What Does Class A Storage Cost?

Class A motorhomes command premium pricing at most storage facilities simply because they require more space. Here's a general range by storage type in 2026:

Pricing in high-cost coastal markets (Southern California, Florida, Pacific Northwest) runs at or above the top of these ranges. In the Midwest and rural areas, you can often find the bottom of the range.

Preparing a Class A for Storage

Class A motorhomes have a few storage prep considerations that differ from smaller RVs:

• Tag axle tires: If your Class A has a tag axle, that's six tires (or more) to cover and protect. UV tire covers for all axles are important for long-term outdoor storage.
• Diesel fuel stabilizer: Diesel degrades more slowly than gasoline but still benefits from stabilizer treatment for storage over 6 months. Fill the tank before storage to minimize condensation.
• Hydraulic leveling jacks: Full-timers are used to deploying leveling jacks wherever they park. For storage, retract them fully and lubricate exposed shaft surfaces to prevent corrosion.
• Large battery banks: Class A motorhomes with lithium battery banks behave differently in storage than lead-acid systems — lithium is more tolerant of partial state of charge but still benefits from maintenance charging. Review your battery type's specific storage recommendations.
• Generator hours: If you use the generator regularly, note the hours and plan a maintenance service if you're approaching the recommended service interval before storage begins.

Finding Class A-Compatible Storage Near You

The best approach is to start with a broad search and then filter aggressively by size compatibility. Not all online facility directories accurately reflect maximum vehicle length — you'll need to call and confirm specifics for any facility that looks promising.

Search for large-vehicle RV storage near you to see facilities in your area, then contact the most promising options directly with your specific dimensions. The facilities that can clearly answer your dimension questions without putting you on hold are usually the ones set up to handle large Class A rigs.
